Alaphilippe, 28, eventually had to bow to Team Ineos’ Egan Bernal with three stages to go in last year’s race.
The cycling season has been re-scheduled due to the coronavirus pandemic with the Tour starting on August 29 with a September 20 finish.
“I’m burning with desire to restart the season to see how I feel and what I can do,” Alaphilippe tweeted.
In a separate statement from his Deceuninck-Quick Step team, Alaphilippe said: “The Criterium du Dauphine is the best preparation for the Tour de France. It will be a unique edition, with many difficult stages, but it doesn’t frighten me.
“I would love to win a stage again, like last year.”
Alaphilippe will begin his term with two races he won last year, the one-day Strade Bianche on August 1 before the Milan-San Remo a week later.
The four-day Criterium begins on August 12 in Clermont-Ferrand before heading east and ending in the Alpine town of Megeve.
Four-time Tour winner Chris Froome, who will leave Ineos for Israel Start-Up Nation in 2021, was ruled out of last year’s race after a crash in last June’s Dauphine where he suffered multiple fractures.
